AIR CLEANER.

'Application ledl May 15,

rilhis invention relates to an air cleaner, yespecially designed and adapted for use=vin 'to get out of order but which nevertheless eectively precipitates and removes from the air all dirt, dust and like particles. A still further object is to provide a cleaner which is of simple and durable construction,

reliable and effective in operation and easy and comparatively inexpensive to .manne facture.

@ther objects and advantages reside in certain novel features of the construction, arrangement and combination of parts which will be hereinafter more fully described andy particularly pointed out in the appended claims, reference being had to the accom p'anying drawings forming a part of this speciication, and in which l41 igure l is aview in elevation showing how the cleaner is associated with an internal combustion engine, u Figure 2 is a view in horizontal section taken on the line 2.-2 oi' Figure 4,

Referring to the drawings and more particularly to Fig. l, ther-numeral l designates an internal combustion engine having a carbureter 2 providedwrth an air intake 3. An air' cleaner embodying the present invention 1928. Serial No. 109,435.

is designated generally at 5, and is connected `up to the air intake 3 ot the carbureter to clean and purify the air drawn thereinto.

rThe cleaner 5 comprises a casing, designated generally at 6, and made up of a bottom wall 7 and side walls 8, a top wall 9 and .end Walls l() and all A horizontal partition l2 is provided in the casing and may be secured in position by having side flanges 13 firmly clamped against the side walls 8 by crimps 14 provided in the side wall. rlhis partition divides the interior of the casing into a cleaning or separating compartment l5 and a dust and dirt compartment 16.

Tn the cleaning `or separating compartment l5 opposed setsoi' baiiies or vertical partitions are provided, one set of baiiies being designated generally at S, land the other set or baiies, being designated generally at S. Each set ofbaiiles is made up of a plurality of substantially l! -shaped baille plates, designated generally at 20, each lil-shaped baille plate having an inclined portion 2l and a straight portion22, the straight portions 22 0 extending straight across the compartment 16 and terminating in curled or curved por-- tions 23X All of the inclined portions 2l encept one are Jfastened to the curled portions E23 ot adjacent battles and the one inclined portion 21 that is not so fastened is extended, as at' 24, and secured as at 25 to 'the casing. The battles thus constructed are arranged in the casing,as shown in Figure Q and extend from the top to lthe bottom of the compartment i5, and when so arranged define a zig zag passage 27 which extends bach and forth across the casing from one end thereof to 'the other. As shown the zig-Zag passage 2i' is of such character' that the air must change its direction of movement in each. run of the passage and at each point where the direction of the air is sharply changed'tlie curved portions 23 of the baiiles occur, and by virtue et their being united with the portions 21 as shown in the drawings, shoulders or projections 28 are provided which assist in the precipitation of the dust and dirt to the door of the compartment l5. rlhe floor et' the compartment l5 which is constituted by the partition l2 is provided with a. dust discharge opening 30 below each pocket 3l which each curled portion 23 of .each baille deiines.

VrThe dust that falls through the discharge openings 30 passes down into the compartment 16 andin order to facilitate the removal of this dust a drawer, designated generally 'Emu lilla at 35, is provided and is slidably fitted in the compartment 16. rlhe drawer 35 is made up et a bottom wall 36, side walls 37, and end walls 38 and 39, the end wall v38 being larger than the draweropening and having gaskets 40 around its margins designed to engage the margins of the drawer/"opening to seal the joint between the end 38 of the drawer and the casing. A handle 41 is provided on the drawer to facilitate its manipulation.` For the purpose ot preventing the air from pass'- ing through the compartment 16 or through the drawer and in eii'ect short circuiting the cleaner, the drawer is provided with a series oit-inclined partitions 4:2 and 43 which divides its interior into isolated spaces 45, there being one such space 15 for each discharge opening 30. 'Thus when the dust drops down into the drawer it is not adapted to be stirred up by the air passing through the cleaner. As shown in liigs. 2 and t the end wall 10 has an inlet opening 50 which communicates with the atmosphere or with any desirable source ot air supply. The end wall 11 has a flanged outlet opening 51 which connects up with the air intake of the carbureter..

lf desirable in each of the pockets 31 constituted by the curled portions 23 ot' the bafes, a delector 60 may be positioned and as illustrated in Figs. 6 and 7, the detlector GO may consist ot' spiral screws consisting ot a central stem or axis 61, around which the spiral vane 62 extends. This defiector does not move but simply serves to aid the device in precipitating the dust or other foreign matter in the air. W' hen the deiiectors 60 are j used the shoulders E28 are omitted.

The form ot the invention shown in lig. 8 is identical with that shown in Figs. 1 to 4 in so tar as the construction and arrangement of bailes in the cleaning compartment ot the casing is concerned but in this embodiment shown in Figs. 8, 9 and 1() the dust-receiving compartment is in the form oi a hopper, as indicated at 7 5 and at its lowerend the hopper 7 5 has a discharge slot 76 which opens into a cylinder 77. 'llhe cylinder 77 slidably receives a cylindrical drawer 78 having its ends closed, as at 79. llhe cylindrical body ot' the drawer 78 has a lengthwise slot 80 which registers with the discharge slot 76 to permit the dust to slide into the drawer. The outer end wall 79 carries a handle v79, In lieu ofthe partitions 4:2 and 43 an inclined baiiie 81 is provided below eachl` discharge opening 30, the balile connecting with the horizontal partitiorr12 and leading from a point in front of each opening 30 downwardly and rearwardly with respect to the same.

A somewhat different arrangement of inlet and outlet forming pockets 31 is provided in that the inlet, which is designated at 82, is located at the bottom of the cleaning `compartment and consists of a cylindrical con-j necting portion 83 and a flaring portion y84.

Leseratte Illhe outlet, indicated at 85, is similarly constructed but couples with the top of the casing.
